yum groupinstall 'Development Tools' yum install qt5-qtbase qt5-qtbase-devel curl-devel
pacman -S base-devel qt5-base curl
As a result, in the build directory will be appears a three subdirectories with a result of compilation. In a ccross-app folder we need a ccross file, in a ccross-curl-executor we need a ccross-curl file. These two file is a main CloudCross executables.
